在黑龙江省五常市境内有个被石头山、石头岭围起来的水库——龙凤山水库。近年,这里出产不少八九斤到二三十斤重的大鲩(草鱼)和五七斤到一二十斤重的大鲤鱼。为钓取这些大鱼,这里的钓友们总是以玉米粒为饵,送钩打窝在水中200米的地方,很是麻烦,尤其在夜里还很不安全。有些没有水上送钩打窝工具的人,只好望洋兴叹。 In the territory of Wuchang City, Heilongjiang Province, there is a reservoir surrounded by Stone Mountain and Stone Ridge - Longfeng Mountain Reservoir. In recent years, here a lot of eighty-nine pounds to two or three pounds of large scallops (grass carp) and fifty-seven pounds to twelve pounds of heavy carp. In order to catch these big fish, the fishing friends here always use corn grain as a bait and send hooks to nest in the water 200 meters, which is very troublesome, especially in the night is still very unsafe. Some people who did not send water hooks to nest tools, had no choice but to sigh.
